Abstract (en)
[origin: EP3546490A1] Disclosed are a catalyst having a high molecular weight by using a novel metallocene catalyst; a method for preparing a polyolefin by using the same; and a method for preparing an ethylene-propylene random copolymer having a high molecular weight and ethylene syndiotactic index and having a small crystal size, thereby having improved transparency during injection. The present invention provides a transition metal compound represented by chemical formula 1.
